Specification forming part of Letters Patent No. 59,017, dated October 23, 1866.

To all whom it may concern:

Be it known that I, CONSTANTINE HIN- GHER, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new and Improved Pipe-Stem 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a longitudinal vertical section of this invention, showing the parts detached one from the other. Fig. 2 is a detached elevation of the conical cup and tube, which forms one of the principal features of my improvement. Fig. 3 is a detached elevation of the cup, which forms the bottom end of the stem.

Similar letters of reference indicate corresponding parts.

This invention relates to certain improvements in that class of pipe-stems on which Letters Patent have been granted to meAu gust 6,1861. In this patent a stem is described with an intervening cup to collect the moisture resulting from the saliva of the smokers mouth and from the condensed smoke, and to prevent said moisture from coming in contact with the tobacco in the bowl.

The present invention consists in the arran gement of a curved tube leading from the upper part of the stem down close at the inner surface of the cup, and bent insuch a manner that when the pipe is laid down' on either side the mouth of said curved pipe is elevated, and the water or liquid in the cup is not permitted to run up into the stem.

It consists, further, in covering the tube which rises from the bottom of the cup with a conical cap, whereby the moisture dripping down from the upper part of the stem is prevented from passing accidentally into the lower part of the stem, and from coming in contact with the tobacco; and, furthermore, by this conical cup the condensing-surfaceis increased, and the smoke is cooled before it reaches the mouth of the smoker.

It consists, finally, in the application to the bottom end of the stem of a secondary cup, which serves as a counter-nut to hold the cork in position, and also to catch such moisture which condenses in the lower part of the stem, and which otherwise would be. liable to run down into the tobacco, and to be smoked over and over again.

A represents a pipestem, made of indiarubber, or other suitable material, in two principal parts, which are united by a screwthread, a. That portion of the stem where its two parts unite forms a cup, B, which is intended to receive the condensed smoke and the saliva running down through the stem from the smokers mouth.

From the bottom part of the cup rises a tube, 1), through which the smoke passes up, and if this tube is not covered the liquid run.- ning down through the upper part of the stem is liable to find its way into said tube to the great discomfiture of the smoker. This difficulty is overcome by the application of a curved tube, 0, extending down from the upper part of the stem close to the inner surface of the cup, and bent so that the liquid running down through it is conducted to the side of the cup and prevented from passing in the tube b.

By curving the tube 0 in the proper direction I gain, also, the following advantage, viz: If the pipe is laid down the liquid previously collected in the cup B is not allowed to run back into the upper part of the stem.

The tube b, which rises from the bottom of the cup is covered with a cone cap, d, which eflectually prevents the moisture dripping down from the upper part of the stem from reaching the interior of the tube 1). This cap can be used in such pipes where the curved tube 0 is not applied; but it also serves to increase the condensing-surface and to cool the smoke before it passes to the mouth of the smoker.

That portion of nicotine or condensed smoke which is always liable to collect at the bottom end of the stem is collected in the secondary cup 6, which I have added to my new stem. This cup is secured by a screw-thread, and it serves also as a counter-nut to hold the cork f in place. It prevents thatportion of the nicotine which is liable to condense in the lower portion of the stem from running back to the tobacco. Y Y

I claim as new and desire to secure by Letters Patent 1. The curved tube 0, applied to the upper part of the cup 13, and operating in combination with the same and with the conical cap (I, applied to the tube (1, which rises from the bottom of the cup B, substantially as and for the purpose described. 7 a

2. The secondary cup 6, in combination with the lower end of the stem A, and with the cork f, constructed and operating substantiall y as and for the purpose specified.
